debugger

Provides the classes necessary to perform parse tracing or create a custom debugger

Overview

Daffodil comes with one prebuilt debugger, the TraceDebuggerRunner, which outputs verbose information during the parsing processes, which can be used to aid in debugging a DFDL schema. For example, the TraceDebuggerRunner can be use like so:

val tdr = new TraceDebuggerRunner()
Daffodil.setDebugger(tdr)

Additionally, one may create their own debugger runner by implementing the methods in the DebuggerRunner.

Once the debugger is set, it must then be turned on, like so:

Daffodil.setDebugging(true);
